Subject: Re: [x86/mm/pat] 8d04a5f97a: phoronix-test-suite.glmark2.0.score
 -23.7% regression

I can also confirm this - just bisected framebuffer rendering
performance regression on amdgpu and
8d04a5f97a5fa9d7afdf46eda3a5ceaa973a1bcc is the first bad commit
(leading to drop from around 260-300fps to about 60fps in CS:GO on
Fury X).

PS. Sorry for duplicate email (sending plain text only now, hopefully).
